GTK tool bar icons in Emacs

GTK tool bar icons in Emacs

[Nick Roberts]

I would like to use the GTK record/stop icons in Emacs.  In GTK Emacs, at
times, the custom icons appear somehow to be replaced by GTK ones.  Could
someone please explain how this works in basic terms.

Also GTK apps, e.g., FireFox often allow names to appear in text below the icons.
(View-> Toolbars-> Customize...).  Is it possible to do this in GTK Emacs?

Thanks,
Nick

The GTK tool-bar code calls `x-gtk-map-stock', which is defined in
lisp/term/x-win.el.  That function is passed the name of an image file,
and returns the name of a corresponding stock image file, or nil if it
can't be found (in which case Emacs uses the original image file).

Can you narrow down what you did when the icons where replaced?  Note that 
many major modes replaces the tool bar, maybe you stubled upon that?

If you need to replace some standard icons, customizing x-gtk-stock-map should 
to the trick (apart from bugs of course).

The tool bar is specified in the variable tool-bar-map.  This can be buffer 
local and as stated, major modes do change this.
or the Gtk+ case, the file names inside tool-bar-map get remapped by 
x-gtk-stock-map to a Gtk+ stock name, so that stock icons are used instead (to 
adjust for Gtk+ theme changes).

The code is not hard to do, the problem is that for icons there doesn't exist 
any short name, only the help text is available.  The text used for the name 
is ofthen too long (for example, "Visit new file..."), and the tool bar 
becomes very wide.

I noticed that, for example the the button gud-goto-info used a gtk icon
("gtk-info") even though the "info" icon was specified in gud.el.  It's
not a problem, I just wanted to use new ones "gtk-media-record" and
"gtk-media-stop" for a new feature of GDB 7.0 (reversible debugging).

Yes, following Yidong's suggestion, I've done that and it seems to work - thanks.

It would be nice to make Emacs more of a GTK app (fonts don't appear to change
with System->Appearance->Fonts->Application font on Ubuntu) but since Emacs
must run on a wide range of platforms that might not be possible.

One thing I've noticed is that if one installs a new fontconfig-handled
font, Emacs can't use it unless you restart, whereas typical gtk apps
can use the new font immediately.

It would be nice if Emacs could see newly installed fonts automatically,
or at least have some way of telling it to re-read fontconfig info
(I tried (clear-font-cache), but that had no apparent effect)...

Thanks,

-Miles
